Overview
The NOBOTECH NPT-PH101 (pH) waterproof pen pH/ORP meter is a Portable measuring instrument for the civilian sector. It uses a 32-bit high-performance processor, which is small in size, light in weight, low in power consumption, and has an IP65 protection rating. It can be tested on the machine, and the operation is convenient and fast.
Features
1. Measurement range: pH 0.00~ 14.00, ORP -999mV~ 999mV, temperature 0~ 60 ℃.
2. LED segment LCD display, which can display pH/ORP value and temperature value simultaneously.
3. Numerical calibrating and Temperature Adjustment.
32-Bit high-performance processor with high Stability and low power consumption.
5. Provide two sets of calibration solution combinations (6.86 and 4.00, 6.86 and 9.18), which can be switched at will.
6. Automatically identify the standard solution. If the standard solution does not match, the calibration cannot be completed.
7. The pH/ORP Measurement mode can be switched freely, and the pH/ORP Electrode Head is easy to replace.
8. Automatic shutdown without button operation in five minutes.
9. Equipped with low battery reminder function.
10. Adopt ultra-long standby technology, with a theoretical standby time of more than one year.
11. Protection Rating IP65.
Principle
The instrument converts chemical signals into electrical signals by sensing the ionic activity or oxygen-reduction potential of the solution under test through its pH/ORP Electrode. The built-in 32-bit high-performance processor processes the electrical signals and combines the temperature data provided by the NTC 10K temperature sensor for automatic temperature compensation. Finally, the pH value, ORP value and temperature value are accurately displayed on the LED screen.
Standards
Protection Rating IP65
Steps
Step 1 Power on.
2. According to measurement needs, freely switch pH or ORP Measurement mode.
3. Electrode head immersed in the solution to be tested.
4. Measured value (pH/ORP and temperature) displayed on LED screen.
5. If you need to calibrate, you can use the two sets of standard liquids supported by the instrument (6.86 and 4.00 or 6.86 and 9.18) for numerical calibration, and the instrument will automatically identify the standard liquid.
6. After use, it will automatically shut down without operation for five minutes.
Notice
• Please make sure to use it under the conditions of Ambient Temperature 0~ 60 ℃ and relative humidity ≤ 90%.
When calibrating, the standard buffer specified by the instrument must be used, otherwise the calibration may not be completed.
• The instrument has an automatic shutdown function. If there is no operation for five minutes, it will shut down to save power.
• When the screen shows a low battery prompt, please replace the battery in time.
• When replacing the pH/ORP Electrode Head, follow the instructions to ensure easy replacement.
• Instrument Protection Rating is IP65, but it needs to be cleaned and dried after use.
• Do not use the instrument for solutions beyond its Measurement range (pH 0.00 to 14.00, ORP -999mV to 999mV, temperature 0 to 60 ° C).
